ELECTRIC HEATER roR'REonss MOUNTINGS.

Application filed June 1, 1926. senai'no. 112,835.

Myinventionrelates to that class of electric heaters which, by reason of adaptation for recess mount1ng,are commonly known as wall-heaters.

1 In. order to comply with safety regulations regarding the installation of heaters of this class, it is advisable that as much of the structure as possible be capable of permanent and precise fitting in such wise as to conform to existing ordinances, rules and requirements; and from this it followsthat provision should be made for the ready and convenient assembling with such permanent portions, of other parts or members which from their nature require repairs or renewals, or which by their-removal afford access to the permanent portions which may require attention. This may be practically carried out by permanently, and in proper and accurate heat insulated arrangement with respect to the frame-timbers of the recess, in-

stalling the shell or casing of the heater, the reflector member and the several ornamental face grids and screens, and adapting the heating member or element for convenient electrical fitting in and removal from the shell, so that it may be renewed or repaired, and access had to the reflector to clean and polish it.

This is the object of my invention, and to this end my invention consists in the novel electric wall-heater which I shall now describe by reference to the accompanying drawings in which I show my heater inits preferred form, it being understood that changes may be made in form and structure without departing from the spirit of my invention as defined by the'claim hereunto appended.

In the drawings Fig. 1 is a front elevation of my wall heater.

Fig. 2 is a vertical section of the same on the line 2-2 of Fig. l.

Fig. 3 is a horizontal section on the line 3-3 of Fig. 1.

1 indicates generally the framing timbers of the wall recess in which the heater. is

fitted.

A pair of spaced brackets 2 are fitted to and project forwardly from the recess-framing-timbers 1, and to these brackets is secured the reflector member 3 of burnished metal, usually copper, backed by asbestos 4:. These parts, namely the brackets 2 and the reflector member 3 comprise, generally, the

shell or casing structure of the appliance, and by their shape," as appears clearly in Fig. 2, they are adapted for accurate and permanent fitting in the wall recess to insure the presence of the prescribed air-insulating space 5, the open frontof which is fittedWith the usual ornamental grids 6.

To the face of the reflectormember, at one side thereof are secured and suitably electrically insulated therefrom by the blocks 7, the electrical contacts 8 which are terminals or poles of the electric circuit.

These terminals are in the form of depend-.

ing metal strips, with spring-hook feet 8';

there are three of them here shown in vertical series, but their number may be varied as deslred.

The heating member comprises an upper heating elements 10 of any suitable nature. There are four such elements here shown, though, obviously, their number may be varied as redetermined. They are'bolted at one of t eir sides at top and bottom to the strips 9 sothat said strips and elements constitute a unit, adapted to be readily fitted to andremoved from its association with the general shell structure; to which end, its top and bottom strips rest upon shelves 11 secured to the reflectorv member. Secured to the heating elements 10, are bars 12 which are of metal and by their proper connection with said elements function as conductors or busbars in the electric circuits. 7

One end of each busbar- 12, in fitting the heating member to rest in place upon the interior shelves 11 of the reflector, slips down into the spring-hook foot 8 of its re spective terminal orcontact 8 and forms and a lower strip 9, united by bolts 9; and 1 13 is the circuit wire conduit and 14 is the conduit box, from which lead the contacts 15 to their connection with the respective terminals 8.

A suitable switch, not shown, may be used for selectively controlling the current. 16 is an ornamental. front screen for the heater. It will now be seen that all those portions of the structure which are adapted for permanent installment may be accurately and with precision placed in the wall recess in conformity with safety regulations, and only that portion, namely the heating member, Which may require removal for any purpose, is adapted to be readily fitted in place; and in so assembling it mechanically, the proper electrical'connection is at once established.

Also by the removal of the heating member,

the reflector is exposed for cleaning and polishing. 1

I claim 1- An electric heateradapted to set into a recess in *a Wall, With its sides, top, bottom and back Walls spaced from correspondshel,l,- a heat against, carried by and following the, con-' tour of the entire rear surface'of the shell,

ing Walls of the recess, and comprising a insulating coverlng lying means carried bythe'shell and projecting below, rearwardly therefrom and above affording stops and supports for regulating the positioning of the shell Within the recess and limiting its proximity to corresponding Walls of the recess, a grille supported by and extending across the front of the shell, anelectric heating element Within In testimony whereof I have signed my 30 name to this specification.
